- Check the company is current and not in liquidation on the Companies House register.
- Confirm FENSA or CERTASS registration on the relevant scheme's own "find an installer" search - membership is per-company and can lapse.
- Get the quote in writing, itemised per window or door, and check the guarantee is insurance-backed.
- Ask for two recent installs you can look at - around Balby, Bessacarr, Cantley or your own street.
